HealthQuest, I can answer one small part of your query. Glucose breath testing only detects SIBO in the earliest part of the small intestine. This is how the lactulose test can be positive while the glucose one is negative. I read this in “Fast Tract Digestion Heartburn”. It makes sense since glucose is one of the sugars that does not cause a lot of gut fermentation. I would say that the lactulose test is the more accurate one for detecting SIBO.
